GATE-HINGE.

SPECIFICATION forming part of Letters Patent No. 448,456, dated March17, 1891.

Application filed August 4, 1890. Eerial No. 360,876. (No model.)

To (LZZ whom it may concern.-

Be it known that LFRANK RUGE, a citizen of the United States, residingat Voonsocket, in the county of Providence and State of Rhode Island,have inventedcertain new and useful Improvements in Automatic GateHinges and Catches; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in gate-hinges, and the noveltywill be fully understood from the following description and claims, whentaken in connection with the accompanying drawings, in which-- Figure 1is a front elevation of a gate and gate-posts embodying my invention.Fig. 2 is a detail horizontal sectional view of the box containing theconcave spring-actuated cam, the said cam, its retraction-springs, and aportion of the gate-frame being illustrated in top plan. Fig. 3 is avertical longitudinal sectional view taken on the line 00 0c of Fig. 2,the central post being removed. Fig. 4 is a view similar to Fig. 2, withthe gate illustrated as open, and Fig. 5 is a horizontal sectional Viewof the post and the frame or casing of the upper hinge, the pivotportion thereof being illustrated in top plan.

In carrying out my invention it is obvious that the several elements maybe constructed of any suitable material and in a manner best conducentto a perfect operation thereof. Referring to the accompanying drawingsby letter, A indicates a gate, which may be of any ordinary or approvedconstruction.

13 B indicate, respectively, the hinge and catch carrying posts. Theseposts B B are respectively composed of an interior solid post I), asbetter illustrated in the sectional views, to which the castingscarrying the hinge and catch mechanisms are attached, and an outer,preferably rectangular, finish or covering, as illustrated, to hide themechanism from view and to protect it from moisture, dust, to.

The rectangular frame or boxing C of the upper hinge surrounds theinterior post I), and is attached thereto and supported at a suitableelevation by means of transverse bolts 0, as better shown in Fig. 5.This boxing 0 is provided on its side adjacent to the gate with. aplatform projection D, which carries adjacent to its outer end anintegral upright pintle E, on which the gate-section. F of hinge ismounted.

I do not desire to limit myself to the form of upper hinge described, asI may employ any form adapted to operate in conjunction with myimprovements, and in some instances I may place a gate-closing hinge atthe top, as well as at the bottom of gate, butI prefer to use at the topof gate a hinge such as described, as the same is especially adapted tooperate in conjunction with my improvements.

The casting G of the lower gate-closing hinge is provided in its bottomand top plates, as better illustrated in Fig. 4, with a rectangularopening to receive the interior post, to which it is attached at asuitable elevation by transverse bolts. This casting G is also providedwith a platform projection II on its inner side, carrying a pintle I toreceive the hinge-section J of the gate, which is rounded at its end ina convex manner to operate in combination with the concave cam presentlyto be described.

Bearing in a seat in the top and bottom plates of the casting G is aguide-post K, which passes through a slot L in the concaved cam M andserves to guide and limit the movement of the same, and at the same timeperforms the function of a pivot therefor. This cam M, which has itsouter edge concaved, as illustrated, is provided on its inner edgeadjacent to its sides with eye loops d, which receive one end ofretracting-springs N, the other ends of which are suitably attached tothe rear wall of the boxing, as illustrated. By this construction itwillbe seen that when the gate is opened the spring on the side adjacent tothe direction of the movement of gate is depressed, while the one on theopposite side is expanded. Now when the gate is released by the personpassing through, the expanded spring will retract, which movement willswing the cam around and cause the opposite corner thereof to bearagainst the side of the gate section of hinge and thus close the gate.

It is obvious from the foregoing description of my improved automatichinge that the same may be mounted upon a post of any ordinary andapproved construction, and I therefore do not desire to confine myselfto the use of the construction described, although such construction ispreferable.

I do not desire to be understood as limiting myself to the preciseconstruction shown and described, as it is obvious that I may make suchchanges and modifications in the several elements as fallwithin thescope of my invention.'

Having described my invention, what I claim is- 1. In a gate-hinge, thecombination, with a pivoted swinging section having its inner endrounded, as described, of a pivotally-mounted spring-actuated camprovided with a concave edge having shoulders extending beyond the pivot-point of the swinging section and adapted to impinge against saidsection, substantially as and for the purpose described.

2. In a gate-hinge, the combination, with a pivoted swinging sectionhaving its inner end rounded in a convex manner, of a cam provided witha longitudinal slot in its body to receive a pivot and guide-post andhaving its front edge concaved to receive and bear upon the rounded endof the swinging section, and retracting-springs having one end attachedto the inner edge of said cam and the other end to the inner Wall of acasing. all adapted to operate substantiallv as specified.

3. The combination, with the post-box or casting provided with therectangular opening for the passage of the interior post and having theplatform projection on its inner side carrying an upright pintle, theguidepost bearing in the top and bottom of said box adapted to take intothe guide-slot in the body of the cam, and the said cam provided on itsinner edge with retracting-springs and having its outer edge concaved,of the swinging section suitably attached to the gate and pivotallymounted upon the pintle of the post-section, having its inner endrounded in a convex manner, substantially as and for the purposedescribed.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK RUGE.
